摘要
Abstract
Using the gas measuring device in National Institute of Metrology of China,the high voltage plateau characteristic curve for LND proportional counter tube was tested,and the experimental results were analysed,the operation conditions of the pneumatic proportional counter was discussed and it was taken as the basis of building gas activity absolute measuring device system.The experimental results show that the plateau area of proportional counter tube is 1 500 ～ 1 700 V,long for 200 V,flat slope about 10％/100 V,so that the performance had failed to meet requirements.It is necessary to design proportional counter independendy.关键词
